Features

  • Double-gate structure with independent sealing system per gate for complete medium isolation during sampling
  • Bidirectional sealing in both forward and reverse directions to prevent backflow
  • Body and key components constructed from corrosion-resistant materials suitable for acidic and alkaline environments
  • Available with manual, pneumatic, or electric actuation
  • Stable sampling flow to minimise media fluctuation
  • Compact structure designed for ease of disassembly and maintenance

Description

A double-gate structured gate valve designed for industrial sampling applications. Each gate features an independent sealing system providing bidirectional sealing to isolate the medium during sampling and prevent leakage or contamination. Suitable for use with acidic and alkaline media in chemical, pharmaceutical, refining, and food processing industries, including reactor sampling under crystallisation conditions.

Selection notes

This gate valve is a double disc and sampling valve pattern, supplied for flanged and butt weld installation.

Sizes run DN25 to DN600, in PN16, PN25, PN40, PN63, PN100, PN160, PN250, PN320, PN400, Class 150, Class 300, Class 400, Class 600, Class 900, Class 1500, Class 2500.

The body is offered in Carbon Steel, Stainless Steel and Alloy Steel, so the grade can be matched to the service rather than the other way round.

Stated service media include acidic media, alkaline media, chemical process fluids, pharmaceutical process fluids and food processing fluids.

It is catalogued for Oil & Gas.

Working temperature is -46°C to 550°C.

Built to API 600, GB/T 12234, GB/T 12224, ASME B16.10 and GB/T 12221.

Specialty Valves configurations

View full Specialty Valves system →
This product is part of the Specialty Valves modular system. All configurations share the same hydraulically operated body: the control function is set by the pilot valve(s) attached. An existing Specialty Valves body in the field can be reconfigured for a different duty simply by swapping the pilot, without replacing the body.
